The best advertisement for Bruno Mars' schizophrenic second album, Unorthodox Jukebox, was that Saturday Night Live sketch where he played a Pandora intern who could do Fallon-level impersonations of pop stars. Once the cuddly soft-rock link between Jack Johnson and Michael Jackson, Mars was thankfully given enough rope to get completely lost in the rest of his record collection. Producers the Smeezingtons already embrace an eclectic, mid-'80s zone where you could hear the effects of new wave on black pop, the effect of hip-hop production on white pop, and the BIg Chill effect of Motown nostalgia on both. Basically, Bruno wants to be everyone on your MTV. Yes, you may have heard he can do the Police ("Locked Out of Heaven") and Prince ("Gorilla"). But did you know he can do Ready for the World ("Treasure"), and Glenn Frey ("Moonshine"), and Paul McCartney's rocked-up cover of Sam Cooke's "Bring It on Home to Me" ("If I Knew"), and Terence Trent D'Arby (a whole bunch of stuff, really). The metaphor falls apart with "Natalie," which is basically the Four Tops' "Bernadette" covered by Linkin Park. C.W.
